"Pretzel Circuit"

Write a blog post COMPLETELY describing today’s activity.  In your post be sure to EXPLAIN what we did, and what each item (the students, the pretzel bag, the pretzels) represented in an electrical circuit.

Today's activity was about electricity circuit. What we did in  class was to pretend to be circuit and one student was the battery, and two another students were the light bulbs. The rest of the class was electrons and as electrons we would give equal amount of pretzels (pretzels=volts) to each light bulb.

"No Wires World"

You live in a world where electricity doesn’t need to flow through wires to light things up or make things work.  Write a paragraph explaining what you would name this world, EXPLAIN one cool thing you could do with electricity without wires, and EXPLAIN one crazy or horrible thing that could happen with electricity floating everywhere.

I would name the world Wireless. I would call the world Wireless because there wouldn't be any  wires around. A cool thing about not having wires is that the electricity would be floating. As they are floating we would be able to see how the electricity moves around. But one bad thing is that we would get am lot people hurt because  they would get electrocuted and we would have a lot of fire too.

"Electricity So Far"

Write and complete the following sentences:

• Electricity is a kind of energy from a current
• So far I learned that electricity can be made by most things
• Electricity is a from of energy because it helps light thing up
• I'm still confused about how electricity is able to move form one place to the other
• I'm getting better at understanding how most electricity needs WORK to actually to work
• I have a question about how the electricity is able to flow through the wires

Another Planet

You have landed on another planet that you live and breathe on (just like Earth!), but it is TWICE as big as Earth.  Create a blog post naming and describing your planet.  In this description, be sure to include a comparison and contrast to the gravity that we have here on earth.

               My planet is called unearth. My planet would have more houses then apartments. My planet would be green with no pollution. My planet would be clean with no trash anywhere and my plant would have more trees unlike earth that you see more apartments and you  barely see trees and everywhere you walk you see trash on the streets. The gravity on my planet is a little more then the gravity on earth so the weight of everything will weight more.

Electric light

Write a blog post completely describe today’s Light the Bulb activity, then explain why you think the light bulb lit up. (How do you think the electricity works to light it up?)

Today we try lighting a light bulb with a wire  and a battery. with one end of the wire you have to put it at the bottom of the battery and the other end of the wire you have to put it on the side of the light bulb and then you have to put it on top of the battery and has to be like a circle so the electric can move. I think that the light bulb light up because the electric needs a flow to pass through the wire around.

“Work vs. Power”

Explain (in your own words) the difference between work and power.  Give an example showing work done with a lot of power and then with a little power.

My understanding of work is a amount  of force you put on a object to move it a distance. Power is the rate which work is done.


Pulling a item up a hill slow and then pushing the item down the hill you would be using a lot of power but dropping the object from the top of the hill is using a little power.

“Balanced and Unbalanced”

Find an example of two free body diagrams, one that is balanced and one that is unbalanced.  For each, describe the forces that are on them and what makes them balanced or unbalanced.


A balanced force is when the net force is equal to ZERO. A unbalanced force is when the net force does not equal to ZERO.

“Free Body Diagrams”

Post a picture or provide a link to a Free Body Diagram you found on line. First, describe what the object is and how it is moving.  Then NAME and DESCRIBE each of the forces that are shown on the diagram.  Make sure your picture is visible once published (or provide a link).




The object is the book and the book has  gravity and normal force. The book has Fg because the book is being push down but the book has Fn as well  because the book is not accelerating downwards.

Friday, November 7-“Vectors & Scalar”

Explain the difference between vector and scalar and find an example of each that we did not cover in class (you can use the internet or pull from your own life)
The difference between vector and scalar is that vector is a quantity that shows direction.
A airplane is vector because it uses direction and acceleration.

Thursday, November 6- “Four Forces”

Describe each of the four types of forces that we did in class in your own words.  For each one, give the description and an example of it in your life

applied force -is when you moves because a person or thing push or pulls something

gravitational force - when two objects are pulled together and one object is earth

normal force - when a surface is being pulled by gravity

tension force -  when a string is pulling an object.

Thu Oct 9 - "GUESS Method" Blog Post

List the 5 steps of the GUESS Method. On each step explain it in your own words and describe what you used to do for this part when doing a written response question.

GUESS                                               

GIVEN- you write down what information the problem gives you

UNKNOWN-what are you missing

EQUAION-write the formula that you will use

SUBSTITUTE- substitute all appropriate information in the equation

SOLVE - you just have to do the math to get your answer

 

Wed Oct 8 - "Speed & Velocity"

Write your own definition of speed and velocity, highlighting the difference between the two. Describe an example of both average velocity and instantaneous velocity in your own life (not one covered in class)
Speed is a distance traveled in a amount of time. Velocity is speed but with a direction. the difference between both is the one has direction and the other does not.

Wed Sep 24 - "Metric Units" Blog Post

• Create a blog post titled “Metric Units” - find at least 3 things in your home or your neighborhood that has metric units.  Describe why you think these things are in metric.

I would say that a bottle has metric units because it is measures the amount per serving of calories, total fat, sodium, total carbohydrate, sugar, and protein. I think this is in the metric units because is in measured in grams. I think that a clock is a metric unit because it is counting by seconds which gives you time. I would say that the length and width of the street is in the metric units because it can be measured in millimeter , centimeter, meter, and kilometer.

Tue Sept 30 - “Distance vs. Displacement”

Describe distance and displacement IN YOUR OWN WORDS (do not write the definition). Give at least one example of each that you noticed throughout your day!

Distance is the length that you have moved in total. Displacement is the total length from the started to the end.In school we walk from fourth class to the cafeteria and then back that is displacement because we walk back to the start position.Everyday we walk and we always have a different distance because we walk to different place. 

Tue Sep 23 - "Estimating Distances"

• Create a blog post called “Estimating Distances” - in it, Estimate the length of the front of your house.  Explain if you think this estimate is reasonable or unreasonable and why.

I estimate that the front of my house is about 378 centimeters long. I think that the estimate of the length of the front of my house is reasonable because my foot is 27 cent and the length of the front of my house is but 14 steps so 27 times 14 equals to 378 cents.

Mon Sept 22 Homework - "Distracted Driving"

• Create a blog post titled "Distracted Driving." In it, explain why you think that distracted driving is bad and describe a time when you were in a car and someone was distracted. What were they distracted by? Did you even notice at the time? How do you feel about it?  

• If you've never been in that situation, then describe what you are most worried that you will do when you become a driver. Why does it worry you?

Distracted driving is dangerous because you and the person in the car with you or the other person in the other car can get hurt or even worst die in the accident.I haven not been in that situation i am worried that i would get distracted by something and hurt someone when i become a diver.It worries me that i can hurt someone when i driver because i can get just distracted  for a second and i can hurt someone by accident.
